Windows 7 PC dying - Countless BSODs

[minyaloth]

So, basically my 64bit Windows 7 PC is starting to die.

It all began with BSOD's related to Kernal_Data_Inpage_Error, referencing ntfs.sys.
That only happened when I overloaded it so I figured it was due to overheating or something.

Then I installed an application called Secunia PSI to try iron out the kinks.
Then this morning I discover that it took the liberty of running windows updates and I was stuck with a new BSOD called process1_initialization_failed. After reading up on some forums that it could be linked to a file called bootcat.cache and deleting it was the best option. I booted into linux and deleted that file and I managed to get into Windows but when I turned my back discovered that the PC had restarted itself so obviously a BSOD had returned.

UPDATE:
I've tried to run windows HDD diagnostic but PC crashes. Tried to run SF Diagnostic tool but PC crashes. If I leave PC on overnight, it's crashed by the morning. With regards to Secunia; It appeared to force windows updates and install a service pack. It was the restart after that service pack that broke it good and proper. Before that the BSOD were only KERNEL_DATA_INPAGE_ERROR crashes and they were only prevalent when I was doing a lot on the PC at a time.

I've also seen posts that said my RAM may be faulty. Should I download and run any specific diagnotics on my RAM?
The below three links are the Files from the last BSOD.
1 is a zip containing both
2 is the .dmp file
3 is the sysdata.xml

Check the memory by using the Memtest86 version 5.01 .iso file. Burn it to a CD or DVD and boot the computer with the disk. Run Memtest86 for at least 7 passes:

Is it really necessary to run 7 passes. It takes ages to run 1

Yes, let it run over night...

If the PC is locked up with a BSOD, it's not like you're going to be using it for anything else, now are you?

Windows Update always creates a restore point. If you can get to the desktop at all, why not do some traveling backwards in time? (This assumes of course,."Secunia" went through the official site).

If you want to do a drive diagnostic, simply stuff the drive into another PC, and check it with that. I think SATA boots in order, (0, 1, 2, etc.), just don't plug in in the zero hole.
